.......Martha's Vineyard is
considered part of Cape Cod, dimwit. Hence the phrase "Cape Cod & the
Islands".

Ummmm.... well, no, actually. The islanders do *not* consider themselves
part of the Cape-not at all!! It is "Cape Cod & the Islands" precisely
because they are different. Nor are they legally joined in any way.
Mainland Cape Cod comprises most of Barnstable County, while Nantucket is
its own - Nantucket County - as is Martha's Vineyard - The County of Dukes
County [yes, that's the correct construction: the county name is 'Dukes
County']
